Dracaena angolensis, formerly known as Sansevieria cylindrica, is a rhizomatous succulent with stiff subcylindrical green-gray leaves that alternate to form a fan-like shape. The leaves are up to 5 feet (1.5 m) tall, up to 1.2 inches (3 cm) in diameter, and taper to a sharp point. They are grey-green with horizontal dark green stripes. The fragrant flowers are white, tinged with pink, tubular with five linear lobes curled backward, and appear arranged in a whorled pattern along an upright, up to 3 feet (90 cm), spike-like inflorescence, usually in spring. They rarely appear indoors and open only at night.
USDA hardiness zones 10b to 11b: from 35 °F (+1.7 °C) to 50 °F (+10 °C).
How to Grow and Care
Place Sansevierias in moderately bright or filtered light. Good locations include a spot in front of a north-facing window or a bright, sunny window covered by a sheer curtain. Although the plant tolerates low light, bright light brings out the colors in the leaves. However, intense light may cause the edges of the leaves to turn yellow.
Allow the soil to dry completely before watering, and then water deeply until water drips through the drainage hole. Allow the pot to drain, and then discard the water that remains in the saucer. Never let the soil become soggy, and never let the pot stand in water. Water sparingly throughout the winter. Like most succulent plants storing water in their leaves, Sansevieria rots quickly in excessively wet soil.
Place Sansevieria at average room temperature. Protect the plant from drafts and cold temperatures as it is damaged below 50 °F (10 °C).
Feed the plant once every three weeks throughout the summer. Use a general-purpose fertilizer for houseplants diluted to half the strength suggested on the container. Sansevieria is a light feeder, and too much fertilizer makes the leaves fall over.
